So, AF is 40 days late now. Ive had no spotting or cramping or anything. These test look like they might have super fain lines but I just dont think they are positive. And if i was pregnant they would be WAY dark by now. Im worried because this has never happend to me before. My cycle is completely normal and AF is always on time. My last one was in November. I had my thyroid removed in June due to cancer, but didnt need chemo or RAI and my doctor said she expected me to be pregnant around December because everything was working perfectly. Anyone have this happen before??? Were you pregnant or not? What was wrong???
